Carbon Monoxide Addition to Ruthenium-Dithiolene Complex and Polysiloxane Hybrid Film Formation.

The addition of carbon monoxide to the ruthenium center of [(η(6) -C6 Me6 )Ru(S2 C6 H4 )] (1) has been investigated. [(η(6) -C6 Me6 )Ru(CO)(S2 C6 H4 )] (2) was obtained by the addition of CO gas to the ruthenium center of 1 in both solution and solid states. 1 was reproduced by treating 2 with an oxidant. A 1/polysiloxane self-standing hybrid film was also prepared and showed a dramatic color change upon transformation of 1 to 2 in polysiloxane hybrid film.
